We've got a whopper of a Radeon on the line today with the AMD HD 6990, featuring dual Cayman XT based GPUs clocked at 830MHz, 4GB of memory, 5-way Eyefinity support right out of the box, and the audaciously named "AUSUM" (Antilles Unlocking switch for Uber Mode) BIOS switch you can flip right on the card itself to unleash the "Uber Mode", bringing the GPU speeds right up to 880MHz each. That's before doing any overclocking of our own! It's a monster right down to its power consumption of a maximum 450W, so good thing it's got brand new PowerTune on-board power regulation.

The HD 6990 promises to be 67% better in game performance than the NVIDIA GeForce GTX 580, supposedly its closest competitor. Hit our HD 6990 launch review to see if it can stand on a class of its own!

What a rip off.699.00 that's a hundred over the hd 5970 when it was released.The only reason it is this high, is the fact that there is no competitive card out there.An extra 2 gigs doesn't cost a hundred dollars.

exactly. thats exactly why it is so expensive. no other card can compete with it, so it doesnt have to have any competitive prices. people would still buy this card though, if they want to get as much performance as possible crammed into as small a space as possible.

As far as price/ performance goes it's definitely not good but not too far off from the gtx 580. It's about 30% faster at 2560x1600, and if you don't play at that resolution there's litte reason to get this beast of a card, and if it's price were linear to the gtx 580 it would be priced at $650 (only $50 off from msrp) If you OC it with the bios switch it bumps it up to almost 35% faster, linear with $675. It's expensive as hell but relative to other high end cards it's not priced too bad.

For comparison the gtx 580 would be ~$385 if price/performance scaled linearly with the 6970 or gtx 570. Or when compared with the 560ti it would be ~$299. As far as being overpriced goes it's all relative and relatively the 6990 isn't too bad, at least in my opinion.
